DUMPING-CAR.

SPECIFICATION forming part of Letters Patent N0.(559,4=O2, dated May 5, 1896. Application filed July 2'7, 1893- Serial No. Z181,600. (N0 model.)

To all whom it may concern.-

Be it known that I, CALEB D. PAGE, a citizen of the United States, residing in Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improve ments in Dumping-Cars, of which the following is a specification.

My invention relates to dun1ping-cars carrying one or more tilting boxes.

It also relates to a dumping-car provided with a frame fixed to the car-truck near the ends, forming, with the doors which close the open sides of the boxes, a casing within which the boxes turn.

It also relates to dumping-cars with a frame fixed to the truck at the end which serves to support the doors when the car is being dumped and to which frame latches are pivoted which serve to hold the box in an upright position.

The object of my invention is to provide a dumping-car with a box or boxes, each supported on a pivotal bearing in thin edge extending longitudinally of the box, with the box securely locked to a fixed portion of the car, preferably at the farthest possible remove from the pivotal point, and further to improve the construction of my car patented November 24, 1891, Patent No. 463,869, and my car patented January 26, 1892, Patent No. 467,772, so that the doors will be automatically transferred from the fixed portion of the car to their closed position on the tilting box, and thus admit of applying my style of door to cars carrying one tilting box only, dumping the entire load on either one'side of the car-body or the other, as may be desired, as well as to double-box cars, dumping part of the load on one side and a part on the other, and to improve the devices for holding the door in position so it can be more readily removed in loading when desired.

I aim also in my improved construction of outer casing to protect the car-box from ooncussion caused by colliding cars.

For the better understanding of my invention reference is had to the accompanying drawings, in which similar letters refer to similar parts throughout the different views.

Figure 1 shows a side elevation of my car; Fig. 2, an end elevation. Fig. 3 shows the which it rocks. Fig. 4 shows a portion of the corner-post of the box with the door-hinge hooked in position thereon. Figs. 5 and 6 show the manner in which the latch engages the post of the car-box to hold the box in an upright position.

In Figs. 1 and 2 the car-truck is surmounted by a casing consisting of the doors D D and an erection at the ends of the box adapted to support the doors when not in engagement with the box, which I prefer to construct in manner shown. It consists of the standards S S, securely bolted to the truck, joined near the lower end by the girth R and at the upper end by the tie-strut U, and of the doors D D.

The draw-sill L is notched down on the cross-sills of the truck, so as to give it a firm hold of the same, and is surmounted by a thin plate of metal on which the T -bar, which supports the box, rocks. T is the axis of the tilting box. I prefer to use as an axis a steel T-bar, though any other suitable form of angular bar may be employed, bolting the wings thereof to the lower side of the'carbox, while the web rests edgewise on the metal plate on which it rocks when the box tilts. This axis projects beyond the ends of the box and is held at each end in position on the draw-sill by a hood 0, Fig. 3, which is so constructed as to prevent lateral motion of the lower edge of the web of the T while allowing the T to rock freely.

I prefer to usefor a hood a solid casting with a recess of suitable size and form to take and confine the end of the axis while allowing the same to rock freely on the metal plate on which it rests. I prefer also to make the axis one continuous piece extending the whole length of the box; but I may decide to use the axis in two or more short pieces or longitudinal sections, leaving one or more open spaces between, and in so doing will not depart from the spirit of my invention. I may also decide to employ an an gle-bar or a channel-bar IOO instead of a T-bar, and can do so without departing from my main idea, which is a dumping-car with box supported on a thin blade or blades of metal projecting beyond the box at the ends sufficiently to be taken by a hood or other suitable confining means, which holds it in position, rocking on a metal surface. The girth R is preferably notched into the draw-sill, thus giving it a secure hold of it. It is so placed that the hood 0 will fit snugly between it and the end of the axis, thus securing it against the force of an end thrust of the loaded box.

The hood 0 is provided with an offset which projects over the girth R and is held in position by a bolt passing through girth, draw-sill, and cross-sill of truck.

The tie-strut U is preferably notched into the posts S S, which should also be notched to receive it. The tie-strut is securely bolted to the posts, thus forming a firm and rigid framework.

To the projecting ends of the tie-struts are pivoted the latches H II, formed with detents which engage the lugs G G on the car-box and serve to keep the car-box in an upright position. They are shown pivoted to the tiestruts on a journal-boss and may be held in place by a split key or any similar device; but I may decide to pivot the latches to the standards S S direct.

Just beneath the latches and extendin g parallel with them, when in their locked position, are the rub-irons B B, which have the twofold purpose of keeping the latches in operative position and guiding the tilting box in its movements past the posts, taking the rub, if any, of the cast posts. They also prevent crush of wood in case the erection at the ends of the box impinges against the iron posts, for this erection is designed not only to support the doors when not in engagement with the box and to carry the latches for locking the box in an upright position, but also to sustain the box ends and to protect them against the concussion of colliding cars. Fig. 6 shows the lug portion G of the cast post P bearing against the rub-iron B.

The box ends are fastened to the posts P P, which are firmly secured to the box-sills. I prefer to make the posts for the corners of the box of cast-iron, forming at the top a lug G, which the holding-latches H H and the hook K of the car-door hinge E engage.

The sides of the tilting box are closed by the doors D D, which are held in position on the car-box at each end by the hook K of the hinges E E and on the lower edge by the strap p, engaging keeper 76.

The door-hinges E E are opposed to the outer edges of the box ends, which at the upper corners are cut to conform to the rounded top of the cast posts P P, and I prefer to form the hinges with a rib which will cover half an inch of the box end. This rib serves as a guide to keep the door in position on the edges of the box ends, so that in restoring the box to an upright position the hooks K K will more readily engage the lugs G G when the door assumes its closed position.

I improve the construction of my car patent No. 37,772 by releasing the door from the fixed portion of the car, and I improve my car patent No. 463,869 by providing the journaled ends of the door-hinges with the open bearings r r, and by providing the hinges with the hooks K K, which engage the lugs G G on the car-box, by means of which the doors are automatically transferred from their supports on the fixed portion of the car to the car-box.

My improved car is operated in the following manner: The latches being down to secure the car-box in an upright position one or both doors can be removed to facilitate loading, and can be replaced when the box is nearly filled. The car being taken to the dumping-grounds, the latches II II on the side opposite that on which the load is to be cast are raised. The box is then tilted, when the projections c e of the hinges E E of the door on the side to which the load is to be cast encounter the holding-pieces 0 r, preventing the further downward movement of the door. The keeper 7c is withdrawn from engagement with the lower end of the strap 1) and the lugs G G from the hooks K K. The door is then free to swing outward with the outward movement of the load, and hangs suspended high above the open sides of the dumped box, through which the load passes as it leaves the car,thus leaving a large opening unobstructed by the depending door. The lower end of the door-hinge E travels along the upper edge of the box ends, and when the box is restored to an upright position the hook K engages the lug G and the strap 19 the keeper 7a. The opening and closing of the gloor is thus automatic.

I may wish to apply my invention to wagons as well as cars, notably when I employ two boxes side by side instead of one.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. A dumping-car with one or more boxes each carrying lengthwise on its base an an glebai' T-bar, or other suitable shape of metal bar having a thin-edged portion which rests on a metal surface on which it rocks and sup ports the box substantially as above set forth.

2. A dumping-car with one or more pivoted boxes fixed to and tilting on the leg of an angle-bar, T-bar, or fixed to and tilting on the thin edge of a metal axis of other shape, the projecting ends of which enter each a recess on the fixed portion of the car which serves to hold the box in position substantially as and for the purposes above set forth.

3. In a dumping-car with one or more pivoted boxes, a casing inclosing the boxes, the two opposite sides of which are doors adapted to close the open sides of the boxes, which doors in operating the boxes are automatically IIO transferred from their supports on the casing to supports 011 the car-box, substantially as above described.

4. In a dumping-car with one or more tipping boxes each of which discharges its entire load on either one of the two sides of the car that may be desired an erection at each end of the box rigidly secured to a fixed portion of the car to which are pivoted latches engaging lugs on the car-box near its upper edge at each of the four corners thereof to secure the box in an upright position, substantially as above described.

5. In a dumping-car with tipping boxes, doors, provided with hooks, engaging lugs on the box ends having supports on a fixed portion of the car on which they rest when not in engagement with the box, substantially as above described.

6. In a dumping-ear with one or more tipping boxes an erection rigidly secured to a fixed portion of the car at each end of the box provided with bearing-surfaces adapted to impinge and bear against the box end near the upper edge thereof without being abraded by it, thus adapting the erection to sustain the box end and to protect it against the concussion of colliding cars without hindrance to dumping the box, substantially as above described and set forth.

7. In a dumping-car with one or more pivoted boxes, doors supported on a fixed portion of the car when not in engagement with the box, provided with hooks automatically engagingand disengaging lugs on the box ends, and provided also with straps automat ically engaging keepers on the box -bottom for the purposes above set forth.

8. In a dumping-car with one or more pivoted boxes, an erection for the support of the doors, consisting of standards bolted to the car-truck, united at top by a tie-strut and near their lower ends by a girth notched into the sill, on which the box-axis rests, and a hood located centrally of said girth for holding the axis-bar of the tilting box in position, substantially as and for the purposes above set forth.

9. In a dumping-car with one or more pivoted boxes, the automatically-closing doors, the latches locking the box in an upright position, and the longitudinally-extending axisbar with thin edged pivot substantially as above described.

10. In a dumping-car with one or more tipping boxes, an erection at the ends of the boxes, extending transversely of the fixed body of the car and rigidly secured thereto, covering the box ends and adapted to sustain and protect them, latches pivoted to the erection, engaging lugs on the box ends near the upper edge thereof, and hooks on the doors, engaging lugs on the box ends, substantially as and for the purposes above set forth.
